Spectrofluorometer

荧光是一种重要的生物物理现象，可以在各种材料中观察到，从有机小分子、无机复合物到合成聚合物、生物大分子和纳米颗粒。理解荧光性质是在分子水平上研究结构、电子和化学性质的重要而有力的方法。因此，荧光光谱技术已广泛应用于科学和工程研究。例如，某些荧光有机和无机化合物可以被合理地设计为能够以超高灵敏度和选择性识别和量化环境和生物重要的化学物质的化学传感器和生物传感器。荧光蛋白可以被引入活细胞中以标记和跟踪生物分子。具有高荧光效率的各种有机共轭聚合物和功能化纳米颗粒可以作为有源组分应用于先进发光器件（LED）的制造中。事实上，荧光材料在现代科学和技术中发挥着核心作用，而这些材料的研究在很大程度上依赖于先进的荧光光谱分析技术。 我们计划购买荧光分光光度计，这将是研究各种荧光特性的重要研究工具。在纪念大学，有许多研究项目需要在校园内使用这些设备。特别是，材料化学，环境工程和加工工程领域的研究人员需要荧光光谱测量来推进他们的研究计划。不幸的是，一个功能齐全的荧光分光光度计在纪念大学是不可用的。使用这一重要的研究工具将大大有利于我们的研究和HQP培训计划。从长远来看，拟议的荧光分光光度计将提供一个技术平台，以加强尖端研究计划，促进新的研究合作，并在多个学科中广泛培训HQP。

Fluorescence is an important photophysical phenomenon that can be observed for various materials, ranging from small organic molecules, inorganic complexes to synthetic polymers, biomacromolecules, and nanoparticles. Understanding of fluorescence properties is a vital and powerful approach to investigate structural, electronic, and chemical properties at the molecular level. As such, the technique of fluorescence spectroscopy has been extensively employed in scientific and engineering research. For example, certain fluorescent organic and inorganic compounds can be rationally designed to act as chemosensors and biosensors capable of recognizing and quantifying environmentally and biologically important chemical species with ultra-high sensitivity and selectivity. Fluorescent proteins can be introduced into living cells to label and track biomolecules. Various organic conjugated polymers and functionalized nanoparticles with high fluorescence efficiencies can be applied as active components in the fabrication of advanced light emitting devices (LEDs). Indeed, fluorescent materials have play a central role in modern science and technology, while the studies of these materials heavily reply on advanced techniques of fluorescence spectroscopic analyses. We plan to purchase a spectrofluorometer, which will be an essential research tool for investigating various fluorescence properties. At Memorial University, there are many research programs requiring an on-campus access to such equipment. In particular, researchers in the fields of materials chemistry, environmental engineering, and processing engineering require fluorescence spectroscopic measurements to advance their programs of research. Unfortunately, a fully functional spectrofluorometer is not available at Memorial University. Access to this important research tool will greatly benefit our research and HQP training programs. In the long term, the proposed spectrofluorometer will offer a technical platform to strengthen cutting-edge research programs, foster new research collaborations, and extensively train HQP in multiple disciplines.
